World Fossil Fuels Depletion

## Introduction

The extraction and reserves data for the curves below were obtained form the Energy Information Agency and a few other sources. The function used to fit the extraction data is a sum of Verhulst functions.

## California

Total to be extracted = 38.4 x 10^{9} barrels; reserves = 9.5 x 10^{9} barrels.

## Colorado

The final peak is assumed to be symmetric, which is unlikely to occur.

Total to be extracted = 6.2 x 10^{9} barrels; reserves = 3.8 x 10^{9} barrels.

## Kansas

The final peak is assumed to be symmetric, which is unlikely to occur.

Total to be extracted = 8.0 x 10^{9} barrels; reserves = 1.5 x 10^{9} barrels.

## Montana

The final peak is assumed to be symmetric, which is unlikely to occur.

Total to be extracted = 3.0 x 10^{9} barrels; reserves = 1.2 x 10^{9} barrels.

## New Mexico

The final peak is assumed to be symmetric, which is unlikely to occur.

Total to be extracted = 8.0 x 10^{9} barrels; reserves = 1.7 x 10^{9} barrels.

## Utah

The final peak is assumed to be symmetric, which is unlikely to occur.

Total to be extracted = 3.0 x 10^{9} barrels; reserves = 1.9 x 10^{9} barrels.

## Wyoming

The final peak is assumed to be symmetric, which is unlikely to occur.

Total to be extracted =7.0 x 10^{9} barrels; reserves = 2.9 x 10^{9} barrels.
